Best International Data SIM Cards for Digital Nomads & Global Travelers [2024]

International Data SIM Cards for Digital NomadsTravelers, digital nomads, and remote-working professionals want to stay connected while traveling abroad. This can be remedied with the use of an international data SIM card.

If you’re in the game of traveling the world or simply working remotely, an international SIM card is probably on your radar. A SIM card that you can use worldwide, one that will generate a new (local) phone number, allowing you to use your phone and access data as you usually would, is an imperative addition to your work and travel arsenal.

The number of people working remotely has skyrocketed over the last two years, along with the necessity of using data over local networks. An international or travel SIM card will allow you the connection when you need it most and has become commonplace for those who travel and move around for work.

Whether professional or personal information, every device we own and access regularly holds details to which we need instant admission. SIM cards are the answer to your mobile carriers’ ability to recognize your phone within the network. If you want your phone to function correctly when you’re traveling, you need an international SIM card, especially if you’re moving around and traveling.

An international SIM card is a perfect alternative to manually connecting to local networks when you’re on a business trip or living and working abroad as a digital nomad cross  many different countries.

While portable routers and pocket WiFi are decent alternatives to an international SIM card, they don’t always have the reliability factor with easy access to local networks. Plus, most global SIM cards reduce or eliminate international communication costs.

However, it’s crucial to do your research before making a choice, so we’ll talk a bit here about the pros and cons of utilizing a SIM card to connect while traveling, the criteria to take into consideration, and the top market alternatives to choose from.

SIM cards vs eSIM cards: How are they different?

First things first: what is an eSIM card? An eSIM card is essentially a digital version of a physical SIM card. The eSIM is a tiny chip that is embedded in your device.This means that it is remotely reprogrammable through the software built into your phone or laptop.

Like most technology, the drive to implement eSIMs was to create more room for things like your phone’s camera and streamline the process of switching carrier plans. Most smartphones made after 2018 have eSIM capabilities. However,  market adoption in the U.S. has been slow due to carrier resistance.

That being said, digital nomads will be happy to know it hasn’t stopped companies from incorporating eSIMs into laptops and tablets. Apple, Acer, Dell, HP, Samsung, and Microsoft all have laptops and tablets that support eSIM or cellular data.

eSIMs, overall, are becoming more and more popular, especially among international travelers.

It’s likely that you have, or have had, a SIM card. The thumbnail-sized chip is easily removable via a port on the side of your phone. If you want to switch phone plans, carrieres, or change your number, you simply remove and replace the SIM.

eSIM’s are a bit different. The eSIM chip is about one-third of the size of a normal SIM meaning that they do not require extra room for a slot. Instead, they are soldered directly into the motherboard of your device.

Unlike a traditional SIM, eSIMs are much more difficult to remove, but are not service specific. This means that switching plans, numbers, or carriers can be managed from the coordinating software installed in your device.

Additionally, a single device can support multiple eSIMs. So, for example, you could include one personal eSIM and one that you exclusively use for business.

Essentially, eSIM and traditional SIM cards carry out the same function. However, the smaller size and embedded function of the eSIM provides added flexibility. Currently, eSIMs are still a long way from completely replacing traditional SIM cards. Instead, they are commonly being used as a second SIM in dual-SIM devices.

International SIM Pros and Cons

A reliable connection to business and family is imperative during a trip, whether for work or play. Before purchasing an international SIM card, you should have a firm grasp of the benefits and downfalls.

International SIM Card Pros

There are plenty of reasons why an international SIM card will work for you while you’re on the road.


With an international SIM card, you only pay for the texts, calls, and messages that you use, not receive. Your carrier will deduct money from your card when calls and messages elicit a response in prepaid situations. Therefore, if that after-hours call from your co-worker comes in and you’re out to dinner or getting ready for bed, you don’t have to pay for it.

Free Incoming Calls

International SIM cards (typically with every service provider) come equipped with free incoming calls, so you never have to pay for who calls you, even when you answer. International communication has always come with notoriously high rates and fees, but the global SIM card eliminates these.

The Application of Local Rates

International SIM cards can save you up to 90% on communication costs when traveling for work through local rates. These local rates apply to text messages, calls, and accessing data. For those constantly using our phones for work, paying local data rates can save tremendous amounts of money.


If you’re working with a travel SIM card, you need to be compatible with your devices. International SIM cards work with most laptops and tablets, but be sure to look into it before you make a purchase and head off on your trip. You want to ensure that you’ll have a connection before you arrive.

Low-Cost Overall

Purchasing a global SIM card will not empty your wallet. While cost varies among manufacturers, buying a prepaid SIM card ranges from $10 to $50, depending on what you want or need from your SIM card performance. In some cases, this initial cost includes talk and text time; in others, it does not.

International SIM Card Cons

Some cons come with an international SIM card, so you’ll want to ensure they don’t outweigh the pros for you upon purchase.

SIM Activity

Most companies do not make you add money to your prepaid SIM monthly to keep it active, but some do. If you travel abroad often, this won’t be an issue. On the other hand, those fees can add up if you use your SIM once or twice a year. Also, you’ll want to choose a provider that doesn’t allow your credit to expire.

International SIM Phone Number

Ask your provider which type of phone number you’ll receive when you purchase your SIM. For example, some companies provide a UK and USA number and then offer the option to add numbers from dozens of additional countries. You’ll need a plan that works for you and your travel schedule.

Roaming Charges

Forwarding your existing phone number to your SIM card number may or may not result in roaming charges for answered calls. The roaming issue is something you’ll want to discuss before purchase, so you don’t have an international SIM card and a ridiculously high phone bill when you arrive home.

Pros and Cons of Sim Cards vs. eSim Cards

Regardless of whether it’s professional or personal, the odds are you need to regularly access your information easily. SIM cards are what makes that possible, so it’s important to do your research.

Here, we’ll talk about the pros and cons of choosing a SIM card vs. an eSIM card. Your goals, the type of traveler you are, and the type of work you need to do while abroad will all impact what kind of subscriber modality works best for you.

Advantages of SIM Cards

Easy to switch devices

If something happens to your device while abroad, having a traditional SIM card is a huge advantage. You can simply remove your SIM, insert it into a new device, and voila. Any information you saved to your SIM card will now be accessible on your new device.

Not trackable

If you have concerns about privacy, having a SIM card is likely the best option. The easy removability of a traditional SIM card makes it easy to get off the grid.

Disadvantages to SIM Cards

New phone number

One of the disadvantages of having a SIM Card while traveling is that you will likely be assigned a new phone number. This may make it more difficult to stay connected with colleagues and friends while on the road.

Less secure

One downside to SIM cards is that they tend to be less secure, especially when compared to eSIMs. If your phone gets stolen, a thief simply has to remove the SIM card and your phone is no longer traceable. In addition, depending on the type of SIM you have, you may have to wait for a new SIM to arrive in the mail.

The advantages of eSIM Cards

The information is rewritable

This means that you can easily change networks without needing a brand new SIM card. For international travelers, this can save hours of time.No more searching for hotspots or trying to communicate through google translate.

Additionally, eSIMs give you the flexibility to temporarily change to other networks. You can switch to an international plan with the click of a button.

Bonus: you’ll never have to go looking for a SIM ‘ejector tool’ to swap out the old SIM.

Temporarily change to other networks

Depending on your device, you could have up to eight digital SIM cards at the same time. This means that you can easily switch between networks or modes. For digital nomads and international travelers, this makes switching to local mobile networks effortless and can save you money.

More secure

Since eSIM cards are embedded in your phone, there are less opportunities for water or grime to do damage to your phone. Additionally, if your phone is lost or stolen it won’t be as easy for thieves to remove the trackable eSIM.

The Disadvantages of an eSIM


The downside to the same secure tracking that prevents theft is that it is more difficult for you to go off the grid. If you have concerns about your privacy, removing the SIM card is an easy solution. However, eSIMs cannot be easily removed which makes you easier to track.

Not easy to switch devices

 Another disadvantage of eSIMs is that they can’t be easily swapped out between devices. If your phone stops working, you cannot simply pull out the card and insert it into a new device. With eSIMs this can become a time-consuming process in which you will need to retrieve and download all your information from the cloud.

Both SIM and eSIM cards have pros and cons. Deciding which one will suit your life and travel style best requires careful consideration.

Criteria to Select Your International SIM Card

If you’re having trouble deciding which travel SIM card will work the best for your trip, there are a few things you should consider.

Your Destination

Where you’re going (one country or many within one region) will determine the best type of SIM card for you. For example, if you’re traveling to just one country, you can purchase a country-specific SIM card.

Trip Length

Consider the length of your trip, and then proceed to add up the number of texts, messages, and data you typically receive in that time frame. It’s safe to say that you’ll use a similar amount when traveling, and you can plan your prepaid SIM package accordingly without overspending.


It’s crucial to consider funding when purchasing anything, and your travel SIM is no exception. You don’t want to overspend and buy more than you’ll need, but not adding enough cash to cover your data use could put you in a serious spot during an important meeting.

Overall, selecting the perfect travel SIM card isn’t difficult, and it can save you plenty of time and money when you’re traveling abroad. Simply know what you need to get out of your SIM and move forward from there.
